My invention relates to` railway vrolling stock and consists in a novel truckv frame construction and arrange-ment" of associated parts. l Y My invention is particularly adapted, for embodiment in affo'ur wheel truckfin which the transoms mount one'end of electric motors also carried in by the'truck axles and in which a relatively movable bolster Iisp'ositioned between the transoms. Y

The objects of my invention areto provide, ina truck of this type, 'for the eiiicientmountdue regard for -the necessary clearances for l? the movement of the bolster, for the applica-- tion and removal of the motor and its` yielding support elements and for the provision` I i n V 15 and 16 respectively of the'transom 2 Which or' suitable vtransom reinforcing members.

f in the truck illustrated in.' Figures 1 to 5, inclusive, and 12, the truekiframe includes wheel pieces 1 and transoms 2 and this frame will'be mounted upon the axles 3 andwheels `12 andl'which are mountedon thetransoni truck as indiv,

lthiough journal boxes (not shown)'jand equalizers 6Y and springs 6a in `any=well known manner. A lspring plank 7 is suspended from transoms`v2 by'links 8 and oarf ries springs 9 upon which the bolsterlO'is' supported inthe usual manner. A motor Vframefll is'mounted on the axleB atfonefend and at its: opposite end' is provided with lugs 2jthroulgh the'elements' described below,

'Preferably, eachtransom 2 comprises 'a flanges 15 fand; 16, respectively, extending the transverse center lireof thetruckfjand 15,l and laofftheftop andf bottom flangges extend toward-thetransverse centerline of theitr'uck, provided for a greater width of iange4 than the usual construction without decreasing the amount of clearance between the. end'lof Vbolster spring bolt 9a and'vertical web V14 and the distance between'the inner edges of the vopposite flanges is slightly great- `er thanthe length ofthe'bolt to allow the latter to lpass therebetweenwhen .positioning vertical web -lt having upper 'and lower p ftowards'the end of the truck.v The portions y the spring 9. A plurality of brackets l17 and y 18 areformed integrally with each transom and extend toward the respective axles 3 and provide upper'fandl'ower. supports for the o spring suspension device comprising barsg19 and 20j engaging: the undersides of brackets 17 andthe upper sides of brackets 1,8,resp`ec-y tivelyfand having coiledvsp'rin'gs 21 corni pressed between xthem. j Preferably, wear plates 22 are positioned between bars19 and 20 and their respective brackets" and suitable: Y 'Y re-.taining pins 23 extend'through the brackw ets, wear plates, barsv and springs. f l, i

The spaced transoms are reinforced longitudinally of thetruck by tie members 3() adjacent; and. below each bracket .18. These tie members reinforce the transoms andxprevent the lower portions of the transoms from moving out of position relative to the motor.

'Eliez-y advantages` oi". the.V above described.' structure;V are most: readily .appreciated by reference to the operation of assembling and with vthe truck frame. motor Vis held in a much higher position than f that shown and is swung to the position indicated; Obviously,` it. could. not be. swung downwardlyfwith the spring. suspension de-` vice in place. and during this swingingmovementntlie-:spring suspension device mustbe moved out. of vertical alignment with the motor frame. lugs .12: and 13.

In Vthe construction illustrated in Figure '6, the-transoms 32 are shown connected by a tie-member 34 located above the level of `the lower bracket 35, tliereby bracing the transom'- web intermediate its upper. and lower flanges.` c c l In' the preerred-structure, the vupper chord of the transom is depressed near the center offtlie truck. In the: modification-illustrated iny .Figures 7 and8, the. top llia-nge 36e-of the. transom is-horizontal.. The lower.v flange 37 therefor. caribe at a@ much. higher level. and spring. suspension. unit S.Y occupies a lower position relative tothe. transom. than inthe preferred form.` To meettliis conditiom the lower; bracket :38. is located b elew.v the, lower flange 37. o the .transonrand-the bracket is providedy with suitable. reinforcing,v ribs- 39 extending inwardly ofjthe transom. web 40.-.

Inftliis form, .the transom `tie 41Y isf-located attlie levelof the bottoinia-nge 37 and above the springplank. 41?..
